74: Thunder Crystal Cannon Salvo

On the Qingyang Ruins battlefield, the situation had been reversed due to the advancement of the Golden Body Corpse Buddha and the expansion of the Rebirth Pure Land Domain.

Where the Domain reached, corpse puppets melted like snow, transforming into pure Death Qi to nourish the Corpse Buddha and the Mo Sect sequence. The Black Fiend Cult members were terrified, their ranks crumbling.

Under the illumination of the Purifying Lotus Sea, the dark golden torrent and violent thunder began a ruthless counter-push and reckoning.

However, the Corpse Refining Sect and Black Fiend Cult had come with their full strength; their foundation was by no means limited to a single Golden Core Elder.

Behind the scattered corpse tide, under those dozen remaining Soul banners, several evil Cultivator leaders at the Foundation Establishment Late Stage were roaring hoarsely, attempting to rally the fleeing troops. Even more exceptionally fierce and massive corpse puppets were driven forward from the rear; they were stitched together from countless fragmented corpses, emitting a nauseating, complex, and venomous aura, attempting to crush the Corpse Buddha's Domain with brute force!

Meanwhile, on the distant horizon, dust and smoke rose again!

Faintly visible were more dark shadows moving; clearly, follow-up reinforcements or reserve troops were approaching!

The enemy's numbers still held an absolute advantage!

Although the Corpse Buddha's Domain was strong, its range was limited. Facing this seemingly endless corpse tide, its purification speed was still struggling.

The war seemed about to fall into a new quagmire of slaughter.

Underground Mo City, Central Plaza.

Mo Yuan's consciousness, like a cold star, overlooked the entire battlefield.

Data streams surged within his Sea of Consciousness: Corpse Buddha Domain efficiency, Spirit Stone consumption, enemy reinforcement estimates, friendly combat losses...

All information converged into a cold conclusion—

A stalemate was not in his favor.

He needed absolute power to crush their courage and shatter their momentum!

One strike to settle the outcome!

"Thunder Crystal Cannon... array... rise."

The cold command, like the key to activating the ultimate weapon, instantly spread to certain specific areas of the underground city.

Rumble...

A thunderous sound, different from the drilling of the Ironclad Earthworm and different from the roaring of Formations—heavier and more filled with mechanical power—erupted from several heavy launch silos pre-constructed in Underground Mo City!

These launch silos were located at key nodes on the edge of Mo City. The silo walls were cast from the hardest Forbidden Spirit Stone mixed with Thunder Crystal fragments, and the interior was covered in complex, rough energy conduction runes.

At this moment, the camouflage rock layer covering the silo openings slowly slid away, revealing deep, dangerous, lightning-flashing holes beneath!

Immediately after, one behemoth after another was slowly lifted from the launch silos, supported by complex mechanical structures and the surging thunder energy beneath!

It was a full one hundred Thunder Crystal Cannons!

Every single cannon looked incredibly ferocious!

The cannon barrels were five zhang long, cast and molded entirely from giant, unpolished Thunder Crystal raw Ore flashing with purple-gold lightning. They retained the natural roughness and sharp angles of the Ore, yet were filled with a sense of power!

Inside the cannon barrels, one could see liquid thunder energy flowing slowly like magma!

On the cannon bodies were engraved thunder magic runes, originating from the same source as the Nine Heavens Thunder Hell Formation, but wilder and focused on destructive output!

These magic runes were currently greedily absorbing the massive thunder energy surging from the energy conduits connected to the cannon bases, which went directly deep into the main trunk of the Thunder Crystal Mine!

Around every Thunder Crystal Cannon, the space slightly distorted due to the highly condensed thunder energy, emitting dull rumbles!

One hundred giant cannons rose simultaneously, the destructive aura they emitted momentarily overpowering the sounds of slaughter on the battlefield, making all living beings feel a palpitation from the depths of their Souls!

"Target... behind the corpse tide... reinforcement assembly point... and all remaining Soul banners..."

"Calculate trajectory... maximize energy output..."

"Prepare for volley..."

Mo Yuan's will, like the most efficient fire control System, instantly completed target allocation and parameter calibration.

The Thunder God Arm lifted slightly; on the deep purple arm, those newly born thunder runes resonated with the magic runes of the hundred giant cannons!

On the ground battlefield, Wang Linger and the surviving Cultivators looked in horror at those terrifying giant cannons rising from the ground, like the Incarnation of the Thunder God's wrath, and felt the earth-shattering energy contained within, forgetting to fight for a moment.

The Corpse Buddha seemed to have received the order as well; the light of the Rebirth Pure Land Domain slightly retracted, focusing on defense and devouring to clear interference for the volley.

"Charge!" Mo Yuan spat out the cold words.

Hum—!!!

The magic runes on the hundred Thunder Crystal Cannons instantly lit up to the extreme!

It was like one hundred purple suns suddenly lighting up over the Qingyang Ruins!

At the cannon muzzles, unimaginable, terrifying thunder energy frantically gathered and compressed!

It emitted a teeth-grinding, sharp hum, as if space itself was being torn apart!

The energy conduits connecting to the underground vibrated violently, the energy of the entire Thunder Crystal Mine being frantically extracted, to the point that the light in Underground Mo City dimmed for an instant!

The light at the muzzles changed from deep purple to blazing white, finally turning into a dark purple-gold color with chaotic gray edges that was impossible to look at directly!

The energy contained within had reached a critical point!

All surviving evil Cultivators and corpse puppets seemed to sense the horror of the apocalypse, letting out desperate wails, instinctively wanting to flee in all directions!

But, it was too late.

"Fire."

Rumble—!!!

The heavens and earth lost their voice!

All things lost their color!

One hundred dark purple-gold beams of light, each over a zhang in diameter and composed entirely of condensed, ultimate destructive thunder, like a whip lashed down by God, instantly tore through the firmament and flooded everyone's vision!

That was not lightning; that was a torrent of thunder!

It was the substance of destruction!

Where the beams of light passed, space distorted and collapsed, leaving behind black trajectories that could not heal for a long time!

The sound was left far behind; only the roar of pure, ultimate energy surging shook the earth, causing it to undulate like waves, and shook all living beings until their ears and noses bled, their Divine Souls on the verge of cracking!

The target area—the reinforcements that had just assembled behind the corpse tide, the remaining Soul banners, those few giant composite corpse puppets—in front of this torrent of destruction, were like bubbles under the sun, without even the qualification to struggle, instantly vaporized!

They disappeared without a trace!

Even the earth beneath their feet was forcibly erased to a depth of several dozen zhang, turning into a huge glazed basin that was smooth as a mirror, flashing with lightning, and flowing with crimson magma!

The shockwave generated by the explosion spread outward like a tsunami, blowing away and tearing apart the corpse tide further away like fallen leaves!

The light of the Purifying Lotus Sea paled in the face of this explosion, which was like the might of heaven, swaying violently!

Even the Golden Body Corpse Buddha's Domain was impacted until it flickered unsteadily!

The entire Qingyang region seemed to have ushered in a brief solar flare!

The light lasted for a full three breaths before slowly dissipating.

When people's vision gradually recovered, what they saw was a dead silence.

In the center of the battlefield, a charred, deep pit of unimaginable size appeared, its edges were crystallized glazed cross-sections, and magma rolled at the bottom of the pit.

The originally dense, endless corpse tide had been evaporated by more than thirty percent by this round of volleys!

Especially the main force and command System in the rear, which had been completely erased!

The remaining corpse puppets lost their unified command and the enhancement of evil arts, falling completely into Chaos and an instinctive, disordered state.

Those Black Fiend Cult evil Cultivators were decimated, with less than one in ten remaining. Even those who were lucky enough to survive were all injured, their minds completely destroyed. Looking at the hundred Thunder Crystal Cannons that were still emitting residual power, with blue smoke curling from their muzzles, it was like looking at true divine punishment; they could no longer produce the slightest thought of resistance.

Won.

A complete, crushing victory.

However, in Underground Mo City.

Mo Yuan slowly retracted the Thunder God Arm.

His expression was indifferent, showing no joy.

Because in his perception, the giant Thunder Crystal Mine beneath his feet, which had originally been surging with energy and flowing with purple-gold halos, had now become dim and lusterless!

The Thunder Crystal clusters, which had originally been as bright as a galaxy, had now all turned into gray-white, lifeless, ordinary rocks!

The energy cycle at the core of the mine, which he had barely maintained after tearing it open, was completely exhausted!

The volley of one hundred Thunder Crystal Cannons had earth-shattering power, but its consumption was also terrifying to the extreme—

It had exhausted more than eighty percent of the Origin energy of the Thunder Crystal Mine!

This strategic resource, enough to support a large Sect for hundreds of years, had been squandered by him in a single strike, almost completely depleted.

The cost was huge.

But the result was perfect.

Mo Yuan's cold gaze swept over the messy, victorious battlefield on the surface.

"Clean up the remnants."

"Recover... all usable resources."

As the order was given, the surviving Mo Sect sequence surged toward the remaining corpse puppets that had lost their command and were in Chaos.

Beneath the glorious victory lay depleted energy reserves.

This newly risen underground Dynasty, while showing its ferocious fangs, also welcomed its first severe resource test.
